by Joshua Abedoza August 04, 2023 7 min read


In this new age of smart generators and portable power stations, EcoFlow has emerged as a front-runner in the realm of portable power technology. Their latest products, the EcoFlow DELTA Pro and the EcoFlow Delta 2, have brought a new level of convenience and efficiency to the world of power management. Today, we will explore these two remarkable units in detail and see how they fare against each other.

Power Outputs and Battery Capacity

 EcoFlow DELTA Pro

The EcoFlow DELTA Pro is the world's first portable home battery with a power output of 3600W, reaching a peak of 7200W, setting the gold standard for portable power stations. This single Delta Pro unit sports a record-breaking 3.6-25 kWh capacity thanks to its brand-new LFP battery. The high kWH capacity makes it the perfect solution for running heavy-duty devices during power outage hits or for regular use.
With the Delta Pro's expandable ecosystem, you can add selection of extra batteries to increase the original capacity. The unit also features a unique protection mechanism which prevents the battery from discharging to a dangerously low level of charge, ensuring longer battery life and less energy loss.

Hey Penny! Yes it will be a max of 500W with solar, or you could get the Delta 2 MAX that can do 1000W because it has two solar charging ports :) If you have any other questions, please give us a call! We’d be happy to chat about all of the available options. 1-844-WILDOAK (1-844-945-3625) or you can chat in as well :) Have a great day!
